Fnb *****ing from their clients

I have a business acc with Fnb from 2012 plus a personal cheque acc. Last year on my business account for bank charges I was paying between R250 to R500. This year fnb is charging me R1275 bank charges on my business acc a month. That is ****************, fnb is *****ing from their clients. Last years turnover was much better and I was paying R500 most bank charges how can it over double the next year. Plus I lost lots of turnover due to covid compared to last year. I had free withdrawals with fnb and now they took away my free withdrawals as they please. Last year when I withdrew cash I only paid R19. 20 for the transaction no matter what amount. This year if I withdraw R8000 they are charging me R260 bank charges. And it changes with every amount. We must slog hard to make ends meet and these ******* fnb sits on their backside and charges R160 per transaction. They forget that it's our money not theirs, they just *****ing our money. R160 costs more than the fuel for that delivery, they are sick upstairs. I'm paying R1500 bank charges for both my accounts with fnb and I'm not going to make these ******* rich anymore. They will lose many clients with their greediness. I will have meetings with other banks and take both my accounts away from fnb to a more reasonable bank. Fnb needs to sort this out and return all ****** funds back into my account.
